This invention relates to improvements in bag holder.

The main objects of this invention are:

First, to provide a bag holder adapted to open and support a bag formed of light pliable material in open position for filling and supporting it in open position in relation to a carton or container.

Second, to provide a bag holder adapted for easy manual manipulation and well adapted for use in the packaging of foods for quick freezing processing or preserving.

Third, to provide a bag holder having the advantages set forth which may be formed of relatively light container board or container stock.

Fourth, to provide a structure having these advantages which may be collapsed for shipment or storage.

Objects pertaining to details and economies of the invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of the invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of a preferred embodiment of my invention shown in operative relation to a bag, the bag being illustrated as formed of transparent material.

Fig. 2 is a perspective view of the bag holder as illustrated in Fig. 1 disposed in filling position on a carton or container. I

Fig. 3 is an enlarged transverse section on line 3-3 of Fig. 1, one of the clamping or holder members being shown in dotted lines.

Fig. 4 is an enlarged fragmentary section on line 44 of Fig. 2.

Fig. 5 is a plan view of the blank of the embodiment of my invention illustrated in Figs. 1 to 4, inclusive, and Fig. 6.

Fig. 6 is a perspective view illustrating the steps of setting up the holder and details of the structure thereof.

Fig. 7 is a fragmentary perspective view of a modified form or embodiment of my invention in collapsed position and positioned within a bag to be supported.

Fig. 8 is a fragmentary perspective view of the holder in its erected position with the bag ready for introduction within a carton.

Fig. 9 is a plan view of the embodiment of my invention shown in Figs. 7 and 8.

Bag holders embodying this invention are well adapted for use in filling bags used to contain food products, the bags being positioned within cartons or containers, particularly for the quick freezing of fruits and vegetables. In many cases the output is too small to justify the expense of carton erecting and filling machines, and owing to the nature of the material it is rather difiicult to place a bag of thin easily fractured material,

'7 Claims. (Cl. 22659) such as commonly used, within a carton and hold it open for filling or extend its walls so that it Will contain the full amount of material it is designed to receive. Further, it is desirable that the fruit or vegetables be packaged with a minimum of bruising or injury. Bag holders embodying this invention enable the attainment of these results.

In the accompanying drawing I represents a carton having closure flaps 2 and 3 on the side walls thereof and end closure flaps 4 illustrated by dotted lines in Fig. 2. The bag or container 5 is formed of suitable waterproof material and is commonly transparent as illustrated.

In the embodiment shown in Figs. 1 to 6 my improved bag holder is formed of a blank of container board or carton material and comprises opposed side walls 25,- end walls 6 and sealing flap 1 at one end of the blank which is lapped upon and secured to the end wall 6 at the opposite end of the blank. The walls and sealing flap are connected by the hinged sections 8 commonly formed by scoring. The side walls have clamping and guide members 9 hingedly connected at I 0 to their upper edges, these members being preferably tapered at their lower ends as illustrated to facilitate the entry thereof into the end of a bag 5, see the dotted line position in Fig. 3. The end walls have spreader members I I hingedly connected to their upper edges at I2, the hinge connection being preferably formed by scoring. These spreader members aredesigned or adapted to be folded inwardly between the members 9, forcing them to fullyerected clamping position as shown by full lines in Fig. 3. The members I I are preferably transversely scored at I3' so that their end portions are inwardly offset to provide an effective engagement with the member 9.

The internal dimensions of the tubular body portion of the holder are such as to fittingly receive the end of the bag when it is expanded or opened as shown in Figs. 3 and 4. After the holder has been applied to the bag the bag is introduced into the container or carton I designed to receive it and the holder is arranged on the end of the carton, preferably between a pair of closure flaps as 2 and 3 in Fig. 2 with the other pair of closurev flaps as 4 in Fig. 2 disposed within the holder as illustrated. This effectively supports the holder and the bag may be filled to its capacity, the holder being released by swinging up the spreader members II and lifting the holder from the bag which drops into the container or, with slight pressure, may be pushed into the container. The end of the bag can then be properly closed and sealed if desired and the container closed. The package is then ready for quick freezing or shipment, as the case may be.

In the embodiment of the invention shown in Figs. '7, 8 and 9 the holder is formed from a blank comprising opposed side walls [4, the end walls and thesealing flap [6 which is secured to the end wall i 5 of; the blank, thus forming a tubular body. The walls 14 are provided with flaps H at their upper ends while the walls l5 have flaps.

H3 at their upper ends. The walls are hingedly connected, preferably by score lines 19 and the.

end walls and end flaps have central. vertical score lines 20 permitting the collapsing 'oiithe. endwalls inwardly and the consequent collapsing of the side walls toward each other as shown in Fig. 7. With the walls collapsedas-shown in Fig; '7 the holder is introduced into the end of a bag Hand the holder is erected by erecting the end walls, that is, by swinging the end wall parts to erected position as shownin Fig.8. The flaps l8 may then be swung outwardly "and when in the fully erected position shown in Fig. 8 serve to hold the holder in erected position.

The lower ends 121 of the side walls are preferably tapered, these tapered portions extending beyond the lower edges of the end walls and facilitating the insertion of the holder within a bag. With the holder inserted within a bag and erected as shown in Fig- 8 it may be introduced. into a carton or container and the bag filled- The holder is released by collapsing or partially collapsing the end walls which disengages not only-the endwalls but the side walls from the bag permitting the holder to be lifted from the carton and .the bag. I havenot attempted toillustrate .or describe other embodiments which I. contemplate and which might bedesirable'for adaptation to particular styles or cartons as it believed this disclosure will. enable those skilled. in the. art to embody or adapt my inventionas may be desired.

Having thus described my invention, .what I claim as new and d'esireto secure by Letters Patent is:

1. A bag holder formed oi an integral blank and comprising side and end walls adapted to receive the open end of a bag, and to supportingly engage acarton, the side walls having bag clamping and guiding members hingedly connected to their upper edges and, depending'within the walls, spreader members hingedly connected to the upper edges ofthe end walls and 'swmga'ble inwardly between the said clamping members whereby the clamping members. are swung outwardly to bag, extending and clamping position-,'said spreader members engagingly retaining said clamping members in clamping position, said holder body portion being, of such dimensions .and cross :section as to receive certain of the :closure flaps of a carton within the. same with other flaps .of the carton disposed on the outerfiside thereof.

6. A bag holder comprising a tubular body of rectangular section adapted to receive the end of a bag, one pair of opposed walls of said body having bag spreading and clamping members swingably connected thereto to depend within the body and having downwardly tapered portions facilitating the entry thereof into a bag, and coacting members swingably connected to the other pair of opposed walls to be swung downwardly between said clamping members for swinging them to clamping position and to engagingly retain the clamping members in clampintegrally and swingably connected to the upper edges of the other pair of opposed walls to be swung downwardly within the body and over the upper edge of a bag within said body.
